It being this tutorial or Team Aikido itself? Tutorial was made for Bushido org and then when Bushido and Team Aikido merged snake added 'by Team Aikido'. This isn't meant to be a '100% copy these moves and you'll get good too!' tutorial, it's to show basic concepts of how to move your tori in the aikido setting to make you look more appealing and skillful and hopefully players are able to learn something and adapt different techniques into their own games.
